Amaron — Regarding the Amaron Go car Battery

I had purchased the battery on Oct 2019 which did not last for not even 2 years. I had called Amaron customer care and they shared one of the service engineers number by name sunil and told if you call he would come down to your location and will fix the issue, but once i called this person he told me to take the battery to the shop and they will check and let you know but once i visited the shop they said 2 cells is down need to charge and check after charging when i called this service engineer he said ok will replace through pro data and let you know. It was almost more than a week no update from that service engineer and when i checked with shop people they said still the battery is kept there no one had come so i called amaron call center, for more that 10 times they keep saying same story service engineer will call back have escalated the issue but no one will turn up.And if you call service engineer he will tell i will check and update but that update will never come up.
Such a hopeless service they provide i don't understand for what reason they provide warranty for the battery . I would suggest not to purchase these peoples battery better to go with other company.
